NEW YORK, A CORPORATION OF NEW 'rrrnwnrrme inncnmn Specification of Letters Patent. PatentedJuly 1922.

Application filed January 21,1920. Serial No. 352,927. I

To all whom it may concern:

vented certain new and useful Improvements in Typewriting Machines,'of which the fol-.

lowing is a specification.

My invention relates to typewriting machines, and more particularly to a so-called portable type of machine which may be readily contracted into compact form in order that it may be conveniently carried .or transported.

The main object of my invention, generally stated, is to provide a simple and efficient machine of the character specified, and one in which parts may be readily contracted from their normal position of use to reduce the cubical dimensions of the machine.

A further object of the invention is to provide a machine of the character specified in whichthe parts when contracted may be fully protected from injury and enclosed within a frame or case and may be thus carried or shipped.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following specification and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views,

Figure 1 is a central vertical fore and aft sectional view of one form of typewriting machine embodying my invention, the parts appearing in positions for use and only so much of the machine being shown as may be necessary to arrive at an understanding of my invention.

Figure Qis a vertical transverse sectional view of the same with parts omitted, the section being taken on the line m-zv of Fig. 1

and looking in the direction of the arrow at said line. I

igure 41s a detall fragmentary transverse sectional view of the machine corresponding to Fig. 2 but showing the parts as they appear when the carriage has been inview of the locking bolt verted and lowered and is ready to be slid or telescoped into the body of the machine. Figure 5 is a side elevation of the machine, shown contracted and closed, ready for transportation.

Figure 6 is a detached detail perspective view of the auxiliary or, case shift frame on which the carriage and its support are mounted.

, tive view of the carriage frame.

Figure 9 is an enlar ed detail sectional for the carriage support together with some of the associated parts.

For the purpose 'of the present invention any suitable printing instrumentalities may. be employed, though I prefer to embody my invention in a front strike typewriting machine in which there is a relative ease shifting movement effected between theplaten and the printing instrumentalties. Certain features of the present invention pertain to case shifting means combined with features whereby the contraction of the machine may be effected.

What may be termed the main frame of the machine is preferably of the non-collapsible or non-folding type and comprises a base 1, fixed side plates 2, a rear fixed cross plate 3, and a front fixed cross plate 3*. When the parts are in the contracted relationship, as shown in Fig. 5, all parts of the machine are confined within the outline of this frame. In the present instance the dimensions of the main frame are not altered by an expansion of the machine or bya contraction thereof. The main frame is adapted to enclose the machine at the bottom, at the rear, at both sides and to partly enclose it on the front side, as at 3*, and when combinedJwith a suitable cover, to entirely enclose the machine and constitute acarrying case therefor.

In the present instance the cover 4 is in the nature of a flexible slat cover of the the rear of the machine, as shown in Fig. l.

The other end of the cover is provided with a catch 6 adapted to be received in a suitable lock 7 secured to the front plate 3" of the frame. Suitable holding devices may be employed to secure the cover against the edges of and against displacement from, the frame. n the present instance each holding device 8 is in the nature of an angle-iron pivoted at 9 to a side plate of the frame, and having a portion or flange 8 which is adapted to overlap the cover and hold it securely in place on the frame. Each holding device may be perforated at 16 to receive a turn-button 10 carried by the frame, The holding devices may thus be locked in operative position. The frame may be provided with rubber feet 11 for supporting the machine, and may also be provided at the front end thereof with a handle 12 to facilitate carrying the machine.

The printing instrumentalities illustrated in the present instance comprise a series of upwardly and rearwardly striking, segmentally arranged, type bars 13 pivoted on a pivot wire 14, suitably supported and held on the main frame of the machine. The heel of each type bar is pivoted to a pull link 15 united at its forward end to a flexible connection 16 of wire or other suitable material. Each wire 16 passes through an openin in a vertically disposed plate 17 secure to or formin part of the main frame. This plate carries a series of grooved guide rollers 18, each of which coacts with and supports a wire 16. Each Wire passes from its roller 18 under a grooved guide roller 19 on a suitably guided stem 20 of the companion printing key 21. The forward end of each wire is anchored to the frame of the machine at 22 beneath a keyboard plate 23. A coiled expansion spring 24 surrounds each wire 16 and bears atone end against the plate 17, and at its opposite end against a collar 25. This spring is effective to return the parts of the associated type action to normal position.

The escapement mechanism for the carriage, and the means for controlling the same from the printing keys are not shown, but may be understood to be of any suitable character, and to be controlled also from a space key or bar 26 operative on a flexible connection 27 similar to the connections from the printing keys to the type bars.

Contained within the main frame and con fined within the outlines thereof is an auxiliary frame, designated as a whole by the reference numeral 28 and shown detached in Fig. 6. This frame is, generally speaking, rectangular in form and constitutes a support for the carriage in both the expanded and contracted position of the latter. and also constitutes a shift frame by which the carriage may receive a bodily case shifting movement as will presently appear. From certain aspects of my invention the means employed for mounting the auxiliary frame 28 in the main frame for case'shift movement, and the means for effecting such case shift movement, may be of any suitable character. As shown in the present instance the skeletonized or cage-like frame 28 comprises upright supporting and guide members 29, 30, 31 and 32, each of which is of dove-tail formation in cross section for reception in correspondingly grooved guide ways 33, 34, 35, 36 respectively on the main frame. The upright members are connected at their upper ends by inwardly extend- 8C ing arms to a longitudinally extending, rectangular, supporting section formed of parallel side members or plates 37 united by cross braces 38, 39 and 40. The lower ends of the uprights 29, 30, are connected to a cross head 41, from which a longitudinally extending member 42 projects, the opposite end of the member 42 connecting with the upright 32. A laterally extending brace 43 extends from the member 42 and connects with the lower end of the upright 31. It will be observed that the parallel side mem bers 37 are connected to the upper ends of the uprights 29, 30,- and 31 by off-set extensions 44, so that these uprights are spaced apart from the. members 37. Below the cross-braces 38 and 39. and between the uprights 29 and 30 and the plates 37 an unobstructed channel, passage or opening extends from one end to the other of the frame 28. 10 The construction of this frame is such that the carriage together with its support, may

be inverted. lowered and moved endwise on or telescoped into the frame 28 as will presently appear. A longitudinally extending grooved track 45 is formed on each of the members 37 and each track extends upward at one end thereof, as indicated at 46. and terminates in a reentrant portion that forms a seat 47 above the upright portion 46 of the track. Both tracks are formed in a like manner, and each is adapted to receive an inwardly rojecting pin 48 adapted to turn and slide t ereon. Each pin extends from a depending lug 49 on a carriage supporting member, designated as a whole by the reference numeral 50 and which is shown detached in Fig. 7. This carriage support is of a length which corresponds substantially to the length of the frame 28, and also corresponds substantially to the width of the latter between the supporting flanges 51 thereon. The carriage support 50 is formed with supporting flanges 52 and 53 which, when the support is in operative position, rest upon the flanges 51 of the frame 28. and the latter thus forms a support for the member 50. I prefer to employ depending positioning lugs 54 on the carriage support, which lugs are adapted to be received bev port against lateral, or fore and aft, displacement from the frame 28. A depending asaaen tween and coact with the side plates 37 of the frame 28, and to hold the'carriage suplug 55 projects from the carriage support 50 at the end thereof opposite that which carries the pins 48. This lug is perforated at 56 to receive the end 57 of a spring-pressed bolt 58, shown in detail in Fig. 9. The stem 59 of this bolt asses through an opening in one end of a s eeve 60 secured to the front plate 37 of the frame 28. The stem 59 is surrounded by a coiled expansion spring 61 which is contained within the sleeve 60 and bears at one end against an end wall of the latter, and at its opposite end against the head 57 of the bolt. The spring tends to force the bolt to locking position indicated in Fig. 9 where it is seated in the opening 56 of the lug 55 on the carriage support and prevents the latter from being turned on the pins 48, or from moving endwise, thus locking the pins 48 in their seats 47.

A depending bracket arm 62 on the carriage support carries a stub shaft or spindle 62 which constitutes a support for a spring drum 63. This spring drum has one end of a cord 64 attached thereto, the opposite end of said cord extending through an opening in an end plate 65 of the carriage and provided with a collar, head or abutment 66. The cord64, in extending from its spring drum 63 to the carriage, passes over a grooved guide,pulley 67 which is carried by the carriage support ,50 adjacent to the opening therein through which the cord 64 passes. The carriage support 50 is formed with outwardly extending ribs 68, which extend longitudinally thereof throughout its length and form tracks that are received within corresponding grooves 69 in the carriage rails 70. These rails are united by the end plates 65 of the carriage to constitute a frame, as shown in Fig. 8, for supporting a cylindrical platen 71. r

Any suitable paper feed 'mechanism may be employed to coact with the platen, paper feed -rollers72 being shown in the present instance co-operating with the platen and extending through openings in a combined paper table and apron 73. Any suitable means are employed to limit the'travel'of the carriage on its support 50, and as hereinbe'fore pointed out, to control the carria e in its step by step feed movements un er control of the printing and space keys.

It will be observed that when the parts are in the expanded or operative position ready for use, as indicated in Figs. 1, 2 and 3 the carriage is supported above the top of the main frame to travel along the carriage support 50 from side to-side of the machine over the auxiliary frame 28 and the main frame and beyond the sides of the latter. At 3 bodily and thereby effecting a bodily case.

shift movement of the carriage. Thus it will be observedI have shown three types, a, b and c on each type bar. It may be as sumed that the types a are lower case characters, types I) are upper case characters or capital letters, and that the types 0 are figures. I have provided for a shift of the platen to either one of two positions from the normal, depending on the operation of a cap. shift key 74, or an operation of a fig. shift key 75. These keys may be connected like the printing keys to suitable actuating devices for shifting the frame 28 and the parts carried thereby upwardly from the normal position. Thus it will be understood that the lower end of the frame 28 bears against the bottom plate 1' of the main frame and is supported thereby. A rod 76 is connected at one end to the upright 32 of the frame 28, and at its opposite end to an upwardly extending lug 77 on the member 42,. and is thus fixed to the frame 28 and maintained spaced apart from the member 42 thereof. An angular lever 78 is pivoted at 79 to alug or support 80 which projects upwardly from the bottom plate 1 of the main frame. The rearwardly extending arm of thislever is slotted at 81 to receive the rod 76, whereas the upwardly extending arm of this lever is perforated to receive a link 82 which extends. freely therethrough, be-

ing provided at its rear end with a headed portion 83. The link 82 is connected to a flexible connection or wire 84 like the printing keys, and is controlledin a like manner by its associated key 75. A set screw 85 is received in a tapped opening in a guide" in which the lower end of the stem of the key 75 .works and limits the downward movement of the key stem, and the case shift devices controlled thereby.

The'cap. shift key 74 is connected in a like manner to a bell crank lever 86 pivoted to a'lug 87 and connected to the rod 76 like the bell crank lever 78. As indicated in Fig. 3 there may be two case shift keys 74 and 75 provided at each side of the machine, the two cap shift keys, and the two fig. shift keys being connected in a like manner to the rod 76 to effect an upward shift of the frame. 28- to which said rod is connected.

The frame 28 in its case shift movements, is

guided by the uprights 29, 30, 31 and 32 working in the grooved guides of the main frame in which said uprights are received and adapted to slide.

Should the operator desire to contract and enclose the machine it is merely necessary to pull the bolt 58 forward against the pressure of the spring 61 with. the aid of the knurled head connected to the bolt 58. The effect of this is to free the bolt head 57 from the depending lug 55 on the carriage support 50. The carriage support may then be turned in a direction at right angles to the axis of the platen on the plus 48 in the seats 47 of the grooved track ways, so as to carry the carriage support out beyond the right-hand side of the main frame and invert the carriage support and effect a corresponding bodily movement of the carriage mounted thereon. The carriage and its support may also be lowered by displacing the pins 48 along the upright terminal portions 46 of the grooved trackways to a position corresponding to that shown in Fig. 4. In order, however, that the carriage and its support may assume this position I provide an opening in one of the side walls 2 of the frame through which the carriage and its support may e inverted and lowered. I prefer to provide for this purpose a hinged door 88 pivoted at 89 to the rear cross plate, and adapted to swing from the closed position indicated in Figs. 3 and 5, where it practically constitutes a continuation with the associated side plate 2 of the frame, to an open position such as is indicated in Fig. 4. The door may be secured in its closed position by a suitable pivoted latch 90 and one of the holding devices 8 may be mounted in place on the door. When the door is open and the carriage and its support are lnverted and lowered to the position indicated in Fig. 4: they may be moved together .endwise or telescoped into the body of the machine, the pins 48 at this time sliding longitudinally along the grooved tracks 45 in the frame 28. When the carriage and itssupport have been moved within the frame 28, and contained wholly within the outer frame, the door 88 may be closed and locked,

and the cover 4 may be drawn forward and" locked and secured in position as hereinbefore described, thus entirely enclosing the entire machine within the main frame, or case and materially reducin the height and the cubical dimensions oft e machine.

From an inspection of Figs. 1 and 5 it will be seen that when the carriage and its support 50 are inverted and telescoped into the machine through one side thereof the carriage and its support occupy a space directly beneath that which they occupied when 1n the operative position, or in posi tion for use.

From what has been said it will be understood that the frame 28 constitutes a support for the carriage; that I have provided means whereby the latter may be inverted, loweredon and moved endwise or telescoped into said support and into the main frame, and that in contracting the machine in this manner the carriage and its support receive a pivotal movement around an axis that lies in a plane extending transversely of the axis of the platen, and also receive a sliding movement in the direction of the len th and travel of the carriage.

arious changes may be made without departing from myinvention and some.features thereof may be employed without others.

What I claim as new and desire'to secure by Letters Patent, is
